Polishing and cleaning tool



April 2l, 1931. L, F, EXLEY y POLISHING AND CLEANING TOOL Filed Dec. l2, 1928 atented pr. 21", 17931' UNITED STATES PATENT ori-ICE v LEO F. EXLEY, OF JOHNSON CITY, NEW-YORK, ASSIGNOR TO ENDICOTT JOHNSON COB.,- I

Y PORATION, OF ENDICOTT, NEW YORK, A CORPORATION OF NEW YORK POLISHING AND CLEANING TOOL lThis invention is a novel revoluble polishing and cleaning tool for burnishing the heads of rivets, bolts, screws, studs, nails, or other predetermined areas without injuring, '5 marring, or marking the adjacent surfaces; and is especially designed for polishing and cleaning the rivetheads in the Shanks of shoe y soles which secure the usual arch supporters, or the rivet heads in such shanks which imitate arch supporters; the tool providing quick and ee'ctive means for doing such work, while vprotecting the surface of the leather shank adjacent suchrivet heads; but it is to be understood that my invention may be used for any purpose for which it is found applicable. I

The arch supporters are usually fastened by means of brass rivets which pass through the shank of the sole, and in nishing the shoe the'bottom of the 'sole is covered with paint or enamel and then polished. Upto the present time, no effective means has been provided for removing from the heads of such'rivets or the like the stains, bleaches, or coloring materials lwith which the entire bottom of the shoe sole has been treated. In the polishing operations yheretofore used the paint or enamel was not removed from the heads of the rivets, lbut in order to make a better looking shoe the enamel or paint was later scraped by hand from the said heads. My invention however provides a tool which will quickly and easily remove the paint or enamel from 'the heads of the rivets in such arch supportershoes.

'Further objects of the invention are to provide, in amanner as hereinafterset forth, a Y Y brush for the purpose referred to, whichis simple in its construction and arrangement; andy is strong, durable, compact, revoluble, controlled by a spring, compressed air, rubber or other suitable means, thoroughly eficient in its use, readily assembled, and comparatively inexpensive to manufacture.

I will explain the invention with reference to the accompanying drawing which illustrates several practical embodiments thereof to enable others to adopt and use the same; and will summarize in the claims the novel '50 features of construction, and novel combinations of parts, for which protection is desired.V f

In the drawings;

Fig. 1 is a perspective view showing one form of my polishing tool operating upon the rivet heads of a sole shank.

Fig. 2 is an enlargedsection through another form of the tool in position for operation showing the adjacent portion of the sole shank and the rivet head, and also showing the adjacent portion of the electric motor used for rotating the tool.

Fig. 3shows the brush of Fig. 2 engaging the rivet head.

Fig. 4 shows in section al modified form of 05 the tool.

Fig. 5 shows in elevation another modified form of the tool. Asshown, the tool comprises aV rotatable shaft 1 having a reduced threaded extension 1a on its outer end'for connecting the axially disposed brush 2, or other polishing or abrading element 7V to the shaft 1, said yshaft being rotatably mounted within a tubular body3 of suitable material, the outer end of which terminates at the reduced portion 1a of said shaft, the body 3 forming a journaly bearing for the shaft 1. The inner end of body 3 is enlarged as at 3b, a shoulder 30 being formed between the portion 3b and the major portion of body 3, for the purpose hereinafterdescribed.

Slidably mounted upon the major portion of body 3 is a tubular guard 4 extending beyond the outer end of body 3, the lower end of guard 4 being conically contracted as at 4a to forma nozzle of diameter tosuit the head of the rivet R or the like which is" to be polished. rlhe inner end of guard 4 is enlarged as at 4Z and slidably engages the enlarged portion 3bof'body 3, a shoulder 40 being formed by the portions 4 and 4b. lVithin the portion 4b around body 3- between the shoulders 30 and 4c -is a coiled spring 5 normally tending to urge the guard 4 outwardly upon the body 3. The movement of guard 4 upon body 3 lis limited by screws 3d passing through slots4cl inthe guard 4, and tapped into the body 3.

Brush V2 is housed within the outer end of 100 the guard 4, and the brush (shown in Figs. 2 and 3) referably has wire bristles and is substantially identical in construction with that shown in my prior Patent No. 1,684,481, issued Sept. 18, 1928, and hence needs no detailed description therein, except to state that the cup shaped head 2a is of substantially same diameter as the adjacent portion of body 3, and is provided with an axially disposed tubular portion 2t which is tapped to engage the treaded portion 1a of shaft 1.

The bristles 2 are secured in the cup shaped head 2a in the identical manner as that set forth in my aforesaid patent. The groups of wire bristles 2 converge at their outer ends and are adapted to fill the opening in the outer end 4a of the guard sleeve 4 (Fig. 3) when the guard 4 is shifted inwardly upon the body 3.

Suitable spacing or adjusting washers 6 may be interposed between the cup shaped head 2a of the brush and the outer end of the major portion of shaft 1 to compensate for material wear on the end of the brush.

Instead kof the wire brush 2, a rod like member 7 (Fig. 4) may be screwed upon the ortion la of shaft 1, the outer end 7a of the brush being repared with any of the wellknown abra ing or bufiing materials and adapted tov engage the head of the rivet.

If desired, the tool may be attached directly to the end bell of an electric motor M as shown in Fig. 2, instead of to the flexible shaft S shown in Fig. 1. In such arrangement it would be necessary to present the work W to the nozzle 4a of the tool instead of presenting the tool to the work. I do not however wish to limit myself to either of the above constructions for obviously a motor E might readily be built into the tool itself, as shown in Fig. 5, making the tool and motor portable and self-contained, in which case the tool could be applied to the work lV which under some circumstances might be advantageous.

In operation a rotating motion is applied to the assembled shaft 1 and brush. By placing the work W to be cleaned against the nozzle 4a of the guard 4, and applying a slight pressure, the guard'4 is caused to move inwardly upon the body 3 and the rotating brush 2 or rod is brought into contact with the rivet R or the like-to be cleaned.

Upon removing the work, the guard automatically returns to its normal position. The guard 4 effectively prevents the brush 2 or rod 7 from coming in contact with the body of the work W and hence prevents the brush from injuring, marking, or marring same, the brush being confined to the rivet head by the guard 4 while at work.

I claim:

1. A machine for polishing heads of rivets and the like in shoe shanks, etc. comprising a. tubular body; a shaft extending through the body; a polishing member carried by said shaft; a shield enclosing the polishing member and slidably connected with the body and normally projecting beyond the end of said member, said shield having an opening the rim of which lies in one plane and approximately corresponds in size to the head of the rivet to be cleaned; means for yieldably holding the shield normally projected beyond the member, while permitting the shield to retract and allow the member to engage the head of the rivet through the opening; said shield protecting the material adjacent the rivet from abrasion by the polishing member; means for limiting the movement of the shield on the body; and means for rotating the shaft.

2. A machine for polishing heads of rivets and the like in shoe shanks, etc.; comprising a. tubular body; a rotatable shaft extending through the body; a polishing member connected with one end of said shaft; a tubular shield enclosing the polishing member and slidably connected with the body and normally projecting beyond the end of said member, said shield having an opening the rim of which lies in one plane and a proximately corresponds in size to the hea of the rivet to be cleaned; spring means for yieldably holding the shield normally projected beyond the member, while permitting the shield to retract as the brush is engaged with the head of the rivet, the shield protecting the material adjacent the rivet from abrasion by the polishing member; and means for initing the movement of the shield on the 3. A machine for polishing heads of rivets and the like in shoe Shanks, etc.; comprisin al tubular body; a shaft extending throug the body and rotatable therein; a brush connected with one end of said rotatable shaft and rotating therewith; a tubular shield slid-- ably connected with the body and having a tapered lower end enclosing the brush and normally projecting beyond the end of said brush, the rim of the opening in the tapered end of the shield lying in one plane and a proximately corresponding in size to tige head of the rivet to be cleaned; spring means for yieldably holding the shield normally projected beyond the brush, while permitting the shield to retract and allow the brush to engage the head of the rivet; said shield protecting the material adjacent the rivet from abrasion by the brush; and means for limiting the movement of the shield on the body.
